Legal Considerations When Using QR Codes
"QR Code" Is a Registered Trademark
"QR Code" is a registered trademark of Denso Wave. Using it in blog posts or conversation is fine, but caution is needed when using it in product or service names.
For commercial use, Denso Wave recommends including "QR Code is a registered trademark of Denso Wave Incorporated." Verify trademark compliance when including "QR Code" in your product names.
Personal Information Handling
Storing personal information in QR codes is subject to privacy protection laws. Putting your own contact in a business card QR code is your choice, but distributing QR codes containing others' personal information requires their consent.
When dynamic QR codes collect scanner location or device information, privacy policy disclosure and consent collection may be required.
Advertising Regulations
Displaying "Scan to win luxury prizes!" next to QR codes is subject to advertising regulations. If actual winning odds or prize details differ from the display, it may constitute misleading advertising.
Campaign pages accessed via QR codes are held to the same legal standards as regular advertising. Being "behind a QR code" doesn't relax regulations.
Protecting Against Misuse
Prepare for risks of third parties misusing your QR codes. Overlay scams pasting fake QR codes over legitimate ones may violate unfair competition and fraud laws, but prevention is key.
Effective measures include regularly scanning your QR codes to verify correct destinations, using tamper-evident seals, and monitoring scan count anomalies with dynamic QR codes.
